找不到终端命令OSX [英] Terminal commands can not be found OSX
问题描述
例如，大多数终端命令不起作用.
A majority of terminal commands don't work, for example .
ls
sudo
vi
ls
sudo
vi
出现错误-bash: ls: command not found，我的路径是echo $PATH
/Users/username/usr/local/bin，我感到不应该存在，但不确定如何进行编辑.
with the error -bash: ls: command not found my path is echo $PATH
"/Users/username/usr/local/bin I get the feeling that " should not be there but not sure how edit it.
路径应该是什么，如何使路径保持不变?
What should the path be and how do I get the path to stay the same?
推荐答案
您需要向$ PATH变量添加更多路径.尝试运行whereis ls并检查命令的二进制文件在哪里.
You need to add more paths to your $PATH variable. Try running whereis ls and check where is the binary of the command.
您可以添加更多这样的路径:export PATH=$PATH:NEW_PATH
You can add more paths like this: export PATH=$PATH:NEW_PATH
